기뻐하며 승리의 노래 (We Will Rejoice)

I played focusing on melody. Did you find out that melody and lyric comes out together when “전심으로 기뻐하리” part comes on? This part, I did not follow the main melody, but went with different melody.  Please refer to sheet if you want to highlight the part, “ 진심으로” or “기뻐 외치며”.
